Question about 2003 Chevrolet Silverado 1500
After oil change oil pressure would peg out when running and stop at 50 to 60 when cut off
The sensor should be near the distributor on the back of the intake.

The pressure to be most concerned with is the reading in gear at idle with engine warmed up...Low end really should not be below 20. If pressure wanders, change the sending unit and check actual pressure with a mechanical gauge if necessary. The age and quality of your oil, as well as temperature all play a part in pressure, as well as internal wear from time & miles of use. If pressure changes with rpm, that is normal. 40psi is good while driving.
need more info just ask.

Hi my name is Tom and I am here to help.
aaah!! the wonderful chevy 350. Probably the best engine ever made. It has had a track record few other engines can match.
Enough of old school. Unless they have moved the sensor in the last 30 years, you should find the sensor below the head 1/2 way to the oil pan.
Remove the electrical connection on the top and using the proper open ended wrench unscrew the sensor. Replace with new sensor and reattached the wire and you are home free.
If I forgot something or I can be of further help feel free to call or email me. Either way, please rank my advice so I can become a better helper in the future.

Hello and welcome. the oil pressure sensor is mounted on the drivers side of engine, top side, behind the intake manifold. kinda hard to find. you will have to look down between the back side of engine and firewall to see it. it is threaded into the block
